Distinguishing places

Regions

The spread of ideas, people, and objects across space and time.

Space is the distance between places/objects.

Time is the measure of crossing that space.

Generally, the farther away something is, the longer it takes for something else to get there. This is called time-space dilation.

Also, generally the farther a message/idea has to go, the less the entire message/idea arrives. (Distance Decay)

The movement of people from one place to another is called migration.

Immigration is movement into a place.

Emigration is movement out of a place.

Ideas spread through a process called diffusion.

There are several types of diffusion: Contagious, stimulus, hierarchical, and expansion.

Contagious diffusion spreads exponentially among groups.

Stimulus diffusion spreads because the idea itself is good, even though the initial method is not.

Hierarchical diffusion spreads from the top of a group down to the rest.

Expansion diffusion occurs as people move and carry their own traits with them into a new area.

People, ideas, and objects move between places.

When people move it is migration.

When ideas move it is diffusion.

Monday we complete the 5 Themes with Human-Environment interaction.
